2.1 Level-Setting Procedure

StudioLive

™

ARc Series

Owner’s Manual

2 Getting Started

Before you begin, here are a few general rules of thumb:

• Always turn down the Main, Control Room, and Phones

level controls before making connections.

• Before plugging or unplugging a microphone while other channels

are active, mute the channel to which you are connecting.

• Channel levels should be set on or near the “U” mark whenever possible. The “U”

indicates unity gain, meaning the signal is neither boosted nor attenuated.

• Do not allow your inputs to clip. Watch the signal indicators and make sure

the red Clip indication illuminates rarely, if ever. Clipping (overloading)

the inputs can result in digital distortion, which sounds terrible.

Warning: Engaging phantom power or connecting sources without muting the channels

can result in a very loud pop that can potentially damage your sound equipment.

Always mute your channels before engaging Phantom power or connecting sources.

P.A. and studio equipment should be powered on in the following order:

• Sound sources (keyboards, direct boxes, microphones,

etc.) connected to the StudioLive ARc inputs

• StudioLive ARc mixer

• Computer (if applicable)

• Power ampliﬁers or powered monitors

When it’s time to power down, your system should be turned oﬀ in the reverse

order. Now that you know what not to do, let’s get some audio going!

2.1 Level-Setting Procedure

1. Grab a microphone and a mic cable and plug them into the

Channel 1 mic input.

2. Connect the Main outputs of your StudioLive ARc to your power ampliﬁer or

powered monitors.

3. Bring down all the level controls on your

StudioLive ARc to the lowest setting.

4. Make sure that the Mic/Line knob on Channel 1 is

turned all the way counter-clockwise.

5. Plug your StudioLive ARc-series mixer into a power outlet and turn it on.

6. If your microphone requires phantom power, engage the 48V button on

your StudioLive ARc mixer.

7. Turn on your ampliﬁer or powered monitors.

8. Speak or sing into your microphone at approximately the same volume you

expect during the performance.

9. Turn the trim knob on Channel 1 clockwise while watching the signal

indicator. Adjust the Channel 1 trim knob until the signal/clip indicator is

red, then back down until it is green and just below clipping at the loudest

input level.

10. Raise the Channel 1 level control to unity gain (denoted with a “U”).

11. Bring up the Main level until you can comfortably listen to your microphone

through your speakers.

12. Sculpt the sound by adding EQ to taste.

3.1 Connections and Controls

3.1.1 Inputs

Microphone Inputs. Your StudioLive ARc-series mixer is equipped with high-gain

XMAX microphone preampliﬁers for use with all types of microphones.

48-volt Phantom Power. The StudioLive ARc mixers provide global 48V phantom

power for all microphone inputs.

WARNING: Phantom power is required for condenser microphones but can

severely damage some dynamic mics, especially ribbon mics. Therefore, unless

the manufacturer of your dynamic mics clearly states that phantom power will not

damage them, you should use condenser mics only, with phantom power on, or

dynamic mics only, with phantom power oﬀ.

Power User Tip: Dynamic microphones and ribbon microphones are generally

lower-output devices and require no external power source. The most important

thing to note about ribbon microphones is that they very rarely require phantom

power. In fact, unless a ribbon microphone calls speciﬁcally for phantom power,

sending phantom power to it can cause severe damage. Condenser microphones

are generally more sensitive than dynamic and ribbon microphones and typically

require external +48V phantom power. Always review your microphone’s

documentation to ascertain the manufacturer’s recommended operating practices.

Line-level Inputs. Each channel of your StudioLive ARc-series mixer has a ¼-inch,

balanced TRS connection for line-level input. Typical examples of line-level

connections are synthesizer outputs, CD/DVD-player outputs, and (with exceptions)

signal-processor inputs and outputs.

Note: As with any mixer, plugging in a microphone or a line-level input device, or

turning phantom power on or oﬀ, will create a momentary spike in the audio output

of your StudioLive ARc mixer. Because of this, it is highly recommended that you mute

or turn down the channel trim before changing connections or turning phantom

power on or oﬀ. This simple step will add years to life of your audio equipment.

Instrument Inputs. Channels 1 and 2 are equipped with an input that can be

switched between line and instrument. Use these ¼-inch connections for

instruments that don’t have internal preamps (guitar, bass, etc.). See Input Source

button in Section 3.2 for more information.

Power User Tip: Active instruments have an internal preamp and a line-level

output. This type of instrument should be plugged into a line input, rather than

an instrument input. Plugging a line-level source into an instrument input risks

damage to the input and results in a very loud and often distorted audio signal.

Insert (AR16c and AR12c). Channels 1 and 2 on the StudioLive AR16c and AR12c

also have inserts. These unbalanced, ¼-inch connectors can be used to connect

external processors (such as compressors, EQs, de-essers, and ﬁlters) to the

channel inputs.

1. Main. The StudioLive ARc-series mixers feature with XLR main outputs.

2. Control Room. These are the balanced control-room outputs.

The Control Room knob on the top panel controls the level.

3. Phones. This ¼-inch TRS connection is for use with headphones.

The Phones knob on the top panel controls the level.

4. Footswitch. This connection allows you to use an external

footswitch (not included) to mute the eﬀects return.

Power User Tip: Your StudioLive will follow the behavior of the type of footswitch

you use. A latching footswitch allows you to mute the eﬀects return until you

engage the footswitch a second time. A momentary footswitch will allow

you to mute the eﬀects return only while the footswitch is depressed.

5. Aux. The StudioLive ARc-series mixers are equipped with 2/2/1 aux

mix outputs. Aux mixes are routed to these outputs. See Section 3.4

for more information on creating Aux mixes for monitoring.

6. FX. The FX send mix is routed to this output, allowing you to create

an additional monitor mix. When this output is engaged, the internal

eﬀects processor is bypassed. More information about creating eﬀects

mixes and the eﬀects processor can be found in Section 3.5.

3.1.3 Rear Panel Connections

USB-C™ compatible connection. Use this port to connect your StudioLive ARc-

series mixer to a USB port on your computer when using the mixer as an audio

interface. See Section 5 for further information. Your StudioLive ARc mixer is a USB 2.0

device and is compatible with nearly all USB connections.

Power-input. Plug in the provided IEC power cable here.

Power switch. Push the top part of the switch to turn on your StudioLive ARc mixer.

Push the bottom part of the switch to turn it oﬀ.

3.2 Channel Controls

1. Input-signal indicator. Each channel features an LED next to the trim control that

illuminates green whenever an input signal is present. The LED color will change to

red if the signal (pre- or post-EQ) reaches -3 dB.

2. Input Gain control. These knobs provide 43 dB of variable gain for mic

inputs and 40 dB of variable gain for line inputs (mono channels only).

3. Input Source button. Channels 1 and 2 oﬀer an Input Source button

that lets you select instrument- or line-level for the ¼-inch inputs

on these channels. Press this button to engage the instrument

preamp when connecting guitars or a passive bass.

Note: Engaging the Instrument preamp will disable the

microphone preamp on the XLR connection.

4. Low Cut Filter (Mono channels only). When engaged, all frequencies

below 100 Hz will be attenuated (cut) at a slope of -18 dB/octave.

Power User Tip: Use the Low Cut ﬁlter to remove unwanted low-frequencies

from your source signal, rather than trying to EQ them out.

The stereo channels are equipped with a +10 dB Boost. When engaged,

this raising the level of both the mic and the line inputs by +10 dB.

5. High shelving EQ Gain control. Sets the level of the high-

band center frequency (10 kHz) from -15 to +15 dB.

Power User Tip: A high shelving EQ is like a treble-control knob on a stereo. In

this mode, the Center Frequency control selects the shelving frequency.

6. Mid peaking EQ frequency control (AR16c and AR12c, mono channels only).

Sets the center frequency of the Mid EQ. You can adjust the center frequency from

140 Hz to 3.5 kHz. This control is available on the Mono input channels only.

7. Mid peaking EQ gain control. Sets the level of the mid-band center frequency

from -15 to +15 dB. The center frequency can be adjusted on the mono inputs of

the AR16c and AR12c. All other inputs and the AR8c have ﬁxed center frequency

at 2.5 kHz.

8. Low shelving EQ gain control. Sets the level of the low-

band center frequency (100 Hz) from -15 to +15 dB.

Power User Tip: A low shelving EQ is like a bass-control knob on a stereo. In

this mode, the Center Frequency control selects the shelving frequency.

9. Aux sends. These are the level controls for each channel to the

corresponding aux mix. The AR16c and AR12c provide two aux

mixes, and the AR8c provides one Aux mix. See Section 3.4 for more

information on using the aux bus to create a monitor mix.

10. FX send. This is the level control for each channel for the eﬀects mix.

See Section 3.5 for more information on creating eﬀects mixes.

11. Pan. This sets the channels position in the Main stereo mix.

Power User Tip: Panning can be a great way to achieve better separation

in your main mix. Using pan in conjunction with level will allow you to

create more deﬁnition and space between each channel’s signal.

12. Mute button and indicator. This button mutes its channel in all outputs.

The LED to the left of it will illuminate red when the channel is muted.

13. PFL (Pre-Fader Listen) button. This button will solo its channel to

the Control Room and Headphone outputs, pre-fader. When no PFL

button is engaged, the Main mix is routed to these outputs.

Power User Tip: If you can’t hear the main mix or a channel in your

headphones, make sure that PFL is not engaged on an unused channel.

14. Channel level. Controls the overall level of the channel.

3.2.1 Digital Returns

The last stereo channel (15/16, 11/12, 5/6) provides a digital playback streaming

option. The Digital Return button routes playback streams 3 and 4 from your audio

software to this channel. When engaged, the analog source will be bypassed;

however, the signal will still be routed to the digital send so that it can be recorded or

processed by a plug-in. For more information, see your StudioLive ARc-series

Software Reference Manual in your My PreSonus account.

Owner’s Manual

3.3 The Super Channel

Each StudioLive ARc-series mixer features a unique Super Channel that allows you to

connect several analog and digital sources at once so you can get the most out of

your mixer.

1. RCA inputs. These unbalanced inputs allow you to connect a stereo

line-level device, such as a Blu-ray player or karaoke machine.

2. 1/8-inch stereo input. This is an unbalanced, stereo, 1/8-inch

connection for line-level devices such as smartphones and tablets.

3. USB / SD Card Return. By default, playback for the onboard SD recorder is

routed to the Super Channel. Engaging this button will route USB playback

streams 1-2 to the Super Channel instead. More information on using your

StudioLive ARc-series mixer as an audio interface can be found in the Section 5.

4. Bluetooth Mute. Press this button to mute the Bluetooth source for

your ARc mixer.

5. Bluetooth pairing. Use this button to pair your Bluetooth device with

your ARc-series mixer. See Section 3.3.1 for pairing instructions.

Power User Tip: All available sources are summed into the Super Channel. Because this

channel only selects line-level devices, the majority of which have onboard level controls,

you can use this channel to expand the input ﬂexibility of your StudioLive ARc-series

mixer.

3.3.1 Pairing a Bluetooth Device

To pair a new device to your StudioLive ARc-series mixer:

1. Press and hold the Bluetooth pairing button for three seconds.

2. The Bluetooth button will ﬂash once every second.

3. Search for new Bluetooth devices from the device to

which you’d like to pair (smartphone, tablet, etc).

4. Select “StudioLive AR16c/AR12c/AR8c” from the available

Bluetooth devices list on the pairing device.

5. The Bluetooth button will illuminate solid when paired successfully.

Note: If previously paired, your StudioLive ARc mixer will connect

automatically. The Bluetooth pairing button will ﬂash rapidly (two to

three times per second) while the Bluetooth module detects connected

devices and will illuminate solid when it is successfully paired.

3.4 Aux Buses

The aux bus provides outputs to route auxiliary mixes that are separate from

the main mix. StudioLive ARc-series mixers are equipped with 2/2/1 aux

buses, which have physical output jacks, and one internal eﬀects bus.

Aux buses can be used for many applications, the two most common of which are

creating monitor mixes and inserting external eﬀects processors into the mix.

Owner’s Manual

3.4.1 Monitor Bus Controls

1. AFL button. This button will solo the aux bus to the aux outputs after the fader.

Power User Tip: Using this control to listen in on a performer’s monitor

mix can be a great way to quickly dial in just the right amount of

each signal and get to a great monitor mix more quickly.

2. Mute button. This button will mute or unmute its aux bus. The LED to

the left of it will illuminate red when the aux bus output is muted.

Power User Tip: Muting an aux bus output during performance breaks is a

quick and easy way to prevent accidental signal spikes or feedback.

3. Output level. Adjusts the master level of the aux output.

3.4.2 Creating Monitor Mixes

Creating custom monitor mixes is critical. If musicians can’t hear themselves or their

bandmates, their performances will suﬀer. A monitor mix can be mono or stereo.

Most often, an individual live monitor mix is mono and is sent to a ﬂoor-wedge or

sideﬁll monitor. (The obvious exception is in-ear monitor systems.) A studio monitor

mix is usually stereo because it is sent to a headphone ampliﬁer that requires both a

left- and a right-channel input. In both cases, the function of the aux bus is the same.

As an example, let’s create a mix for Aux Bus 1:

1. The Aux 1 send control for each channel sets the send level in the Aux 1 mix.

Use these knobs the same way that you use the output level controls to dial

in your main mix. Ask your musicians what they would like in their monitor

mix and use their requests as a starting point.

2. Use the Aux 1 Output control to adjust the overall output level.

3. Press the Aux 1 AFL button to listen to the mix through the headphone or

control room outputs as you make ﬁnal adjustments to the mix.

3.5.2 Internal FX Bus Return

The internal FX return allows you to adjust the amount of the eﬀects

output you would like in your main and monitor mixes.

1. Aux sends. These are the level controls for the eﬀects output in each aux

mix. The AR16c and AR12c provide two aux mixes; the AR8c provides one

aux mix. See Section 3.4.2 for more information on creating aux mixes.

2. Balance. This sets the FX return’s position in the main stereo mix.

3. Mute button. This button will mute or unmute the FX return. The LED

to the left of it will illuminate red when the FX output is muted.

Power User Tip: Mute the FX return during performance breaks while the

band is speaking to the audience to create a more professional show.

4. FX level. Adjusts the master level of the eﬀects output in your main mix.

3.5.3 Creating Internal Eects Mixes

There are at least two main advantages to creating an eﬀects mix, rather than

inserting an eﬀect in a channel. First, several channels can be sent to a single

processor. In addition to greatly simplifying the number of parameters you

have to control, this can create a cohesive sound in your mix. The second

advantage of creating an eﬀects mix is that you can vary the level sent from

each channel to the processor, rather than patching the output directly into the

eﬀect. This allows you to add a lot or a little of an eﬀect to any given channel.

Your StudioLive ARc-series mixer’s internal eﬀects bus is used much in

the same way the aux buses are used to create monitor mixes.

1. To begin, select the eﬀects preset you would like to use by turning the

Eﬀects encoder to the desired number and pressing the encoder.

2. Raise the FX return output level to unity.

3. Use the FX send controls on each channel the same way that you use the

faders to set the output level to your main mix. The higher a channel’s

level is in the eﬀects mix, the more processed (“wetter”) it will sound.

Let’s say that you are using reverb to liven up a relatively dead room.

You might send a little bit of each input to the reverb, but you probably

will not want much of the drums and bass to be processed, as too

much reverb could reduce their impact and leave your mix without

a sturdy foundation. So rather than turning the FX-send level for the

kick drum channel all the way up, turn it to the 8 or 9 o’clock position,

so that its saturation is between 20% and 30%. This way, only a small

portion of the kick-drum input will be aﬀected by the reverb.

4. Use the FX return level fader to increase or decrease

the overall eﬀects mix in the Mains to taste.

5. To send the FX return mix to a monitor mix, adjust the

FX return’s monitor send control to taste.

3.5.4 Using an External Eects Processor

This section will detail how to use an external eﬀects processor,

bypassing your StudioLive ARc mixer’s internal processor.

1. To begin, connect the FX output to the input of your external

eﬀects processor and connect the outputs of your processor

to a stereo channel on your StudioLive ARc mixer.

2. Turn up the output level of the stereo channel to unity.

3. Use the FX send controls on each channel the same way that you use the

faders to set the output level to your main mix. The higher a channel’s

level is in the eﬀects mix, the more processed (“wetter”) it will sound.

4. Use the stereo channel’s Level control to increase or decrease

the overall eﬀects mix in the Mains to taste.

5. To send the FX return mix to a monitor mix, adjust the

stereo channel’s monitor send control to taste.

Power User Tip: You can also use the FX output to create an additional monitor mix

when multiple monitor mixes are of greater importance than adding eﬀects.

3.6 Master Section Controls

1. USB 1-2 Send. By default, the main mix can be recorded to your computer on the

last USB send pair (17-18 / 13-14 / 7-8). If you are only recording the main mix on

your computer, engaging the USB 1-2 Send button will simplify setup in most

situations.

Note: When this button is enabled, Channels 1 and 2 cannot be recorded

individually, although they will still be a part of the Main mix.

2. Main Mute button. This

button will mute or unmute the Main bus. The LED to the left of

it will illuminate red when the main outputs are muted.

Power User Tip: Muting the main mix during performance breaks is a

quick and easy way to prevent accidental signal spikes or feedback.

3. Output-level control. Adjusts the master level

of the Main output.

4. Main output meters. These peak meters display the output levels of the main

stereo bus. These meters are scaled from -24 to +15 dBu. For best performance, the

highest level of your mix should stay between the “0” and “+6” indicators.

Because the StudioLive ARc mixer main outputs

are electrical, rather than digital, it is more advantageous to meter them

relative to voltage. The Main meters display signals from -24 to +15 dBu

(-42 to -3 dBFS). This means that if you play back a digital signal over USB

or from the SD card at -18 dBFS, it will register in the Main meters as 0 dBu.

Conversely if you record a signal over USB that registers at 0 dBu in the Main

Meters, it will display at -18 dBFS in any application that meters in dBFS.

3.6.1 Control Room Levels

StudioLive ARc-series mixers feature a headphone output and control-

room outputs, allowing you to listen to the main mix and the Solo

bus. Whenever a channel is soloed, it will automatically be routed

to the control room and headphone outputs. When no channel is

soloed, the main mix will be heard through these outputs.

4 SD Recording and Playback

StudioLive ARc-series mixers are equipped with an onboard stereo SD recorder

that allows you to record the main mix as a stereo WAV ﬁle to any FAT16-

formatted SD card or FAT32-formatted SDHC card. You can also load stereo

WAV and MP3 ﬁles onto an SD or SDHC card to play audio during a show.

4.1 SD Recording

This section explains on how to record the main mix as a stereo WAV ﬁle:

1. Insert a FAT16-formatted SD card or FAT32-formatted SDHC card into your

StudioLive ARc mixer. An SD card will provide up to 2 GB of storage space.

An SDHC card will provide up to 32 GB.

2. Press the Record button.

3. Recording will begin when the Play/Pause and

Record buttons are both illuminated.

If no SD card is recognized, the Record button will ﬂash three times.

4. Press the Play/Pause button to stop the recording.

Once complete, you can transfer your recordings onto your computer by

inserting the SD card into your computer’s SD card reader and copying the

ﬁles to your computer’s hard drive. Each ﬁle will be labeled with an “SL-ARc”

heading, followed by a number.
